Titre : Fine mapping of Xq11.1-q21.33 and mutation screening of RPS6KA6, ZNF711, ACSL4, DLG3, and IL1RAPL2 for autism spectrum disorders (ASD) Type de document : Texte imprimé et/ou numérique Auteurs : Katri KANTOJARVI, Auteur ; Ilona KOTALA, Auteur ; Karola REHNSTROM, Auteur ; Tero YLISAUKKO-OJA, Auteur ; Raija VANHALA, Auteur ; Taina NIEMINEN-VON WENDT, Auteur ; Lennart VON WENDT, Auteur ; Irma JARVELA, Auteur Année de publication : 2011 Article en page(s) : p.228-233 Langues : Anglais (eng) Mots-clés : ACSL4 autism spectrum disorders DLG3 gene IL1RAPL2 linkage RPS6KA6 single nucleotide polymorphism ZNF711 XLMR Index. décimale : PER Périodiques Résumé : About 80% of cases with autism express intellectual disability. Both in autism and in mental retardation without autism the majority of the cases are males, suggesting a X-chromosomal effect. In fact, some molecular evidence has been obtained for a common genetic background for autism spectrum disorders (ASD) and X-linked mental retardation (XLMR). In several genome-wide scans (GWS), evidence for linkage at X-chromosome has been reported including the GWS of Finnish ASD families with the highest multipoint lod score (MLS) of 2.75 obtained close to DXS7132 at Xq11.1. To further dissect the relationship between autism and genes implicated in XLMR, we have fine-mapped Xq11.1-q21.33 and analyzed five candidate genes in the region. We refined the region using 26 microsatellite markers and linkage analysis in 99 Finnish families with ASD. The most significant evidence for linkage was observed at DXS1225 on Xq21.1 with a nonparametric multipoint NPLall value of 3.43 (P = 0.0004). We sequenced the coding regions and splice sites of RPS6KA6 and ZNF711 residing at the peak region in 42 male patients from families contributing to the linkage. We also analyzed ACSL4 and DLG3, which have previously been known to cause XLMR and IL1RAPL2, a homologous gene for IL1RAPL1 that is mutated in autism and XLMR. A total of six novel and 11 known single nucleotide polymorphisms were identified. Further studies are warranted to analyze the candidate genes at Xq11.1-q21.33.

Titre : Psychopathology and cognitive performance in individuals with membrane-associated guanylate kinase mutations: a functional network phenotyping study Type de document : Texte imprimé et/ou numérique Auteurs : K. BAKER, Auteur ; G. SCERIF, Auteur ; Duncan E. ASTLE, Auteur ; P. C. FLETCHER, Auteur ; F. L. RAYMOND, Auteur Article en page(s) : p.8 Langues : Anglais (eng) Mots-clés : Cognition Dlg3 Genetics Intellectual disability Maguk Psychiatric disorders Index. décimale : PER Périodiques Résumé : BACKGROUND: Rare pathogenic variants in membrane-associated guanylate kinase (MAGUK) genes cause intellectual disability (ID) and have recently been associated with neuropsychiatric risk in the non-ID population. However, it is not known whether risk for psychiatric symptoms amongst individuals with ID due to MAGUK gene mutations is higher than expected for the degree of general intellectual impairment, nor whether specific cognitive differences are associated with disruption to this gene functional network. METHODS: This study addresses these two questions via behavioural questionnaires and cognitive testing, applying quantitative methods previously validated in populations with ID. We compared males with X-linked ID caused by mutations in three MAGUK genes (PAK3, DLG3, OPHN1; n = 9) to males with ID caused by mutations in other X chromosome genes (n = 17). Non-parametric and parametric analyses were applied as appropriate to data. RESULTS: Groups did not differ in age, global cognitive impairment, adaptive function or epilepsy prevalence. However, individuals with MAGUK gene mutations demonstrated significantly higher psychopathology risks, comprising elevated total problem behaviours, prominent hyperactivity and elevated scores on an autism screening checklist. Despite these overt difficulties, individuals in the MAGUK group performed more accurately than expected for age and intelligence quotient (IQ) on computerised tests of visual attention, convergent with mouse models of MAGUK loss-of-function. CONCLUSIONS: Our findings support a role for MAGUK genes in influencing cognitive parameters relevant to psychiatric risk. In addition to establishing clear patterns of impairment for this group, our findings highlight the importance of careful phenotyping after genetic diagnosis, showing that gene functional network disruptions can be associated with specific psychopathological risks and cognitive differences within the context of ID.
